Abstract
The utility model discloses a liquid crystal display screen protection cover structure, which comprises a transparent board, the front of the transparent board is covered by a front protective film, the circumference of the back of the transparent board is provided with gum, which is covered by a piece of release paper, and the back of the transparent board is covered by a rear protective film positioned within the glum. When the protection cover structure is mounted, the front side of a liquid crystal display screen is covered by the protection cover structure; during mounting, the front and the back of the transparent board are always provided with the protective films, the rear protective film is taken off in the last step, the gum is utilized to stick the protection cover structure on the metal frame of the display screen, two dust-proofing strips positioned on the circumference of the inner side of the gum are clamped between the metal frame and the transparent board, so that a closed space is formed in front of the liquid crystal display screen, and thereby dust can be effectively prevented from entering; during mounting, the cleanliness of the transparent board cannot be affected as well, and thereby the image quality of the display screen is guaranteed.
Description
Technical field
The utility model relates to a kind of LCDs shield structure.
Background technology
For the accurate small household electrical appliance that has Liquid crystal module, in case dust enters Liquid crystal module inside, be easy to cause liquid crystal color image quality to descend, in production and use, it protected at present, inevitably picture quality is exerted an influence during use.
Summary of the invention
The purpose of this utility model provides a kind of good dustproof effect, image is not shown the LCDs shield structure that exerts an influence, overcomes the deficiencies in the prior art.
LCDs shield structure of the present utility model; transparent plate body is arranged, be covered with preceding diaphragm in the front of transparent plate body, periphery posts gum in the back of transparent plate body; the gum outside is covered with peeling paper, and the inboard that is positioned at gum in the back of transparent plate body is covered with the back diaphragm.
LCDs shield structure of the present utility model has the crack, limit between the periphery of wherein said back diaphragm and the gum, and the width in crack, described limit is the 1-2 millimeter.
LCDs shield structure of the present utility model; the assembling back cover is in the LCDs front side; transparent plate body front-back has diaphragm all the time during assembling; in the end a step is taken off the back diaphragm; utilize gum that this guard shield is sticked on the display screen metal framework; between metal framework and transparent plate body, be positioned at the gum inner peripheral and clamp two circle dust excluders; make the LCDs front side form the space of sealing; prevented entering of dust effectively; also can not influence the cleaning of transparent panel during assembling, guarantee the picture quality of display screen.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is an A-A sectional schematic diagram shown in Figure 1.
Embodiment
As shown in Figure 1, 2: 1 is transparent plate body, selects acrylic board (PMMA plate) for use.Diaphragm 2 before the front of transparent plate body 1 is covered with one deck, and preceding diaphragm 2 is the electrostatic protection film.Periphery is covered with gum 3 in the back of transparent plate body 1, is that outside surface is covered with one deck peeling paper 4 in the back of gum 3, and wherein gum 3 and peeling paper 4 can be selected double faced adhesive tape for use.Diaphragm 7 after the back of transparent plate body 1 is covered with one deck, and back diaphragm 7 is the electrostatic protection film.Leave crack, limit 8 between the periphery of back diaphragm 7 and the gum 3, the width in crack, limit 8 is the 1-2 millimeter.
Final step peels off and removes back diaphragm 7 with peeling paper 4 during installation; utilize gum 3 that this guard shield is sticked on the LCDs metal framework all around; the peripheral clamping in inboard (or outside) that is positioned at gum 3 between this metal framework and transparent plate body 1 has external seal bar and sealing strip; form two circle dust excluders, play good sealing effectiveness.Wherein sealing strip is whippy Polon material.
